| 摘 要： | 本文基于软件无线电思想和正交变换算法的理论，从正交分解的数学计算出发，依次对调幅、调频等模拟调制信号以及幅度键控、频移键控、相移键控等数字调制信号作了分析，得出每个信号经正交分解后所形成的同相分量与正交分量，并对其进行了总结归纳。最后在TMS320C5402芯片上实现了解调算法的程序设计。

| Abstract: | This article is based on the theory of software radio and orthogonal demodulation algorithm, and have made analysis to AM, FM, ASK, FSK, PSK ect, embarking on the theory of orthogonal transforming . It has analyzed the synchronism and the quartered component which each signal orthogonal decomposes, and has carried on the summary induction to it. Finally complete the multi demodulation with the software on the TMS320C5402 chip. |
